Further development of the zygote depends on
A. Type of life cycle of organism
B. Environment to which it is exposed
C. Type of fertilization through which it is formed

Options

A. A,B and C
B. A and C only
C. A and B only
D. B and C only

Answer

To determine the factors that influence the further development of a zygote, we need to analyze the given options:

1. **Type of life cycle of organism (Option A)**:
- The life cycle of an organism dictates how the zygote will develop. Different organisms have different life cycles (e.g., complete metamorphosis in insects, direct development in some amphibians). This affects the stages the zygote will go through, such as cleavage, gastrulation, and organogenesis. Therefore, the type of life cycle is a significant factor in the development of the zygote.

2. **Environment to which it is exposed (Option B)**:
- While the environment can influence the overall health and viability of the zygote, it does not directly determine the developmental pathway of the zygote itself. The genetic and biological processes that guide development are primarily intrinsic to the zygote and its species. Hence, this option is less relevant when considering the direct factors affecting zygote development.

3. **Type of fertilization through which it is formed (Option C)**:
- The method of fertilization (internal vs. external) plays a crucial role in the development of the zygote. For example, organisms that undergo external fertilization often have different developmental strategies compared to those that undergo internal fertilization. This can affect how the zygote develops, including the conditions it requires for successful growth. Thus, the type of fertilization is also an important factor.

Based on this analysis:
- Option A (Type of life cycle of organism) is correct.
- Option C (Type of fertilization through which it is formed) is also correct.
- Option B (Environment to which it is exposed) is not a direct factor.

Therefore, the correct answer is that the further development of the zygote depends on both A and C.

**Final Answer**: The correct option is A and C only.
